ussl – SSL/TLS module¶
This module implements the corresponding :term: A subset of the CPython module, as described below. For details, refers to CPython document: ssl
This module provides access to transport layer security (formerly known as “secure socket layer”) encryption and peer authentication tools for client and server-side network socket.
Functions¶
-
ssl.wrap_socket(sock, server_side=False, keyfile=None, certfile=None, cert_reqs=CERT_NONE, ca_certs=None)¶
Use sock (usually a usocket.socket instance of type SOCK_STREAM), And return an instance of ssl.SSLSocket, which wraps the basic stream in an SSL context.
The returned object has the usual stream interface methods, such as read() ，write() etc.
In MicroPython, the returned objects do not expose socket interfaces and methods, such as recv()，send().
In particular, server-side SSL sockets should be created from ordinary sockets returned on accept() non-SSL listening server sockets。
Warning
Some implementations of the module do not verify the server certificate, which makes the established SSL connection prone to middleman attacks.
